Version 7.2 1171 Mediant 1000B Gateway & E-SBC
User's Manual 65. Configuration Parameters Reference
Parameter Description

User Side:

0-63: Static TEI is used.

127: Dynamic TEI allocation is supported (TEI request
procedure initiated).
configure voip > interface bri > tei-
assign-trigger
[BriTEIAssignTrigger_x]
Defines when to start the TEI assignment procedure.
The valid values are (bit-field parameter):
 Bit#0: LAYER1_ACTIVATION
 Bit#1: BRI_PORT_CONFIG
 Bit#2: CALL_ESTABLISH
The default is 0x02.
Note: The parameter is applicable only to the User side (for
Dynamic TEI).
configure voip > interface bri > tei-
remove-trigger
[BriTEIRemoveTrigger_x]
Defines the following:

Network Side: When to "forget" all existing TEIs and wait for
the User side to start a new TEI assignment procedure.
This is also applicable to static TEI.
 User Side: When to start a new TEI assignment verification
procedure.
The valid values are (bit-field parameter):
 Bit#0: LAYER1_DEACTIVATION
 Bit#1: BRI_DL_RELEASED
 Bit#2: TEI_0_P2MP_NET_SIDE
The default is 0x00.
NFAS Parameters
(Note: The parameters are applicable only to PRI interfaces.)
NFAS Group Number
configure voip > interface e1-t1 >
isdn-nfas-group-number
[NFASGroupNumber_x]
Defines the ISDN Non-Facility Associated Signaling (NFAS)
group number (NFAS member), per trunk.
 [0] = (Default) Non-NFAS trunk.
 [1] to [12] = NFAS group number.
Trunks that belong to the same NFAS group have the same
number. With NFAS, you can use a single D-channel to control
multiple PRI interfaces.
Note:
 For the parameter to take effect, a device reset is required.
 The parameter is applicable only to T1 ISDN protocols.
 The x in the ini file parameter name denotes the trunk
number, where 0 is Trunk 1.
 For more information on NFAS, see ISDN Non-Facility
Associated Signaling (NFAS) on page 495.
D-channel Configuration
configure voip > interface e1-t1 >
isdn-nfas-dchannel-type
[DChConfig_x]
Defines primary, backup (optional), and B-channels only, per
trunk.
 [0] PRIMARY= (Default) Primary Trunk - contains a D-
channel that is used for signaling.
 [1] BACKUP = Backup Trunk - contains a backup D-
channel that is used if the primary D-channel fails.
 [2] NFAS = NFAS Trunk - contains only 24 B-channels,
without a signaling D-channel.
